DUST-COLLEGTING SHI ELD FOR HEATING-RADIATOR.

Patented Nov. 21, 1911.

Application filed February 11, 190 9, Serial No. 477,389. Renewed January 27, 1910. Serial No. 540,471.

To all whom it may concern:

Be it known that I, CHRISTIAN W. G. SODEMANN, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Dust-Collecting'Shields for Heat-.

ing-Radiators, of which the following is a specification.

My invention'relates to a dust collecting shield for heating radiators, and has for its object to provide a deflecting shield to be adapted to steam radiators or hot water tive view of a device embodying my invention in place upon a radiator, showing a portion of the upper extremity of the deflector broken away and the dust collecting device also broken away. Fig. 2 is a vertical sectional view of the dust collecting device. Fig. 3 is a similar view of a modified form of the same. Fig. 4 is an enlarged detail view in perspective of the turning mechanism whereby the dust collecting device is loweredto discharge the dust accumulated therein.

As shown in the drawings, my device comprises a deflector 5 which is mounted upon the rear side of a steam or hot water radiator and whose upper portion-extends upwardly and forwardly in the manner well known in the art; the back of the deflector being formed of the sheet 6 which is curved over uponitself at its-upper edge to form a roll 7. A trough 8 is mounted immediately to the rear of the roll 7 by means of the hinge pin 9, and at its outer. edge the trough 8 is provided with a projecting flange 1O which is curved at its outer end to form the roll 11 encircling the rod 12, which terminates at each end in a crank 13, which cranks are mounted in the side pieces 14' through the apertures 15'. At their ends the cranks 13 are provided with knobs 14 accumulated within the trough. The trough 8 is provided at each end with the end-gate 15 which is of such width as to keep the.

germs, and where no deflector is employed,

or a deflector having no dust collector is employed, said particles are kept in constant agitation and circulation through the atmosphere of the room. The device of my invention consequently serves to steadily accumulate such particles and to cause their removal from the room; the heat generated by the radiator serving to keep said particles agitated and to convey them to the trough.

The. trough 8 isnormally kept in its closed position by means of the spring 16.

The deflector 5 illustrated in the drawings may be any of the commercial forms of deflector now used in connection with steam and hot water radiators, the device of my invention being susceptible of ready attachment to any of the ordinary commercial forms of deflector. When it is desired to remove the dust accumulated in the trough 8, the free edge of the said trough is operated downwardly to discharge the dust and when released is restored to'its original seat by means of the tension of the spring 16.

Having thus fully ,described my invention, what I claim as new and desire to have secured to me by the grant of Letters Patent, is:

In a dust collecting shield for radiators, the combination of a deflector adapted to be mounted on the back of a radiator and having its upper end inclined forwardly and upwardly above the radiator, a dust collecting trough pivotally mounted transversely at the upper end of the deflector and being curved at its outer end to form a roll, said trough being provided with end gates of such height as to keep the trough depressed from the under side of the deflector to provide an aperture to admit dust to the trough, a crank mechanism pivotally mounted upon b in, and means for holding the trough in northe deflector and having pivotal connection \ihhme to this specification, in presence of two with the trough at its rolled end, said crank "subscribing witnesses.
